Definitions
- This invention relates to a capsule rupture printing system for recording an image in an image-receiving sheet with a layer of subminiature capsules.
- U.S. Pat. Nos. 4,399,209 and 4,440,846 and U.K. Pat. No. GB2,113,860 to The Mead Corporation describe an imaging system wherein a photosensitive layer comprising microcapsules containing a photosensitive composition in the internal phase is image-wise exposed to actinic radiation and subjected to a uniform rupturing force whereupon the microcapsules rupture and image-wise release the internal phase.
- An image-forming agent such as a substantially colorless chromogenic materials are typically associated with the microcapsules such that when the microcapsules rupture the chromogenic materials are able to image-wise react with a developer material and produce a color image.
- An object and advantage of the present invention is to provide a novel color printing system which can increase the speed of printing many copies of the same one image.
- Another object of the present invention is to provide a novel color printing system which includes a means for making a plurality of large size monocrome pictures which are converted from output electrical signals of the computer and used for image original.
- FIG. 1 is a system construction representing one embodiment of the present invention
- FIG. 2 is a system construction representing another embodiment of the present invention.
- FIG. 3 is a sectional view of the imaging sheet used in the present invention.
- FIG. 4 is a sectional view of the image-receiving sheet used in the present invention.
- FIG. 5 is an explanatory view showing the sensitive spectral of the imaging sheet.
- FIG. 3 shows a simplified structure of the imaging sheet used in this invention.
- Reference symbols A 1 , A 2 , A 3 denote microcapsules presenting colors of cyan, magenta and yellow, respectively.
- Chromogenic materials a 1 , a 2 , a 3 which generate cyan, magenta and yellow, respectively, and reactive composition b 1 , b 2 , b 3 which immobilize the chromogenic materials by changing the viscosity etc. as a result of reaction to electromagnetic beams of which wave-lengths ⁇ 1 , ⁇ 2 , ⁇ 3 correspond to the colors of the chromogenic materials (see FIG. 5) such as light beams, are microcapsulated by surrounding thin films C made of gelatin etc.
- the microcapsules are coated evenly on the surface of the sheet 27 forming carrier so as to constitute an imaging sheet 1.
- the imaging sheet 1 When the above mentioned imaging sheet 1 is exposed to the light having the wave-lengths to which the reactive composition b 1 , b 2 , b 3 , within the microcapsules A 1 , A 2 , A 3 react, the viscosity of the reactive composition b 1 , b 2 , b 3 changes. Then, the imaging sheet 1, thus exposed, is united with the image-receiving sheet 2 into one body and pressure is added to the united body so that the capsules A 1 , A 2 , A 3 are broken. As a result, there comes out a difference in the amount of the chromogenic materials flown out of the capsules between the capsules exposed to light and those unexposed. Consequently, colors corresponding to the wave lengths ⁇ 1 , ⁇ 2 , ⁇ 3 of the projecting light are presented on the image-receiving sheet 2. That is, color patterns in accordance with the patterns presented at the time of light projection can be obtained.
- FIG. 1 shows one embodiment of the present invention.
- Microcapsules sealing therein a photo-reactive composition and a chromogenic materials which generates a color upon reaction with a developing materials applied on an image-receiving sheet 2 are applied on an imaging sheet 1.
- Back-tension is applied to this imaging sheet 1 by rollers 11 in order to form a flat surface portion onto which a later-described image original is to be projected.
- a pressure roller unit 3 is disposed downstream of the flat surface portion, and while the photosensitive surface of the imaging sheet and the developing materials-coated surface of the image-receiving sheet 2 face each other in superposition, the microcapsules are ruptured, color generation proceeds and an image or the like is outputted.
- Reference numeral 4 represents a transparent film subjected to treatment for providing a film such as PET film with uniform chargeability.
- a charging device 15 is disposed in the outer periphery of a photosensitive drum 6 to charge the surface of the photosensitive drum positively.
- Reference numeral 5 represents a laser scanner unit, which radiates a laser beam on the surface of the photosensitive drum 6 on the basis of output signals of an image data processing circuit or output signals of a computer, not shown, to remove the charged charge and to form the latent image of the image. Then, a toner is deposited to the charge removal portion by a developing unit 14 to form a toner image. The toner image thus formed on the surface of the photosensitive drum 6 moves in synchronism with revolution of the photosensitive drum 6 and is transferred onto the transparent film 4 by an adsorption unit 17 which is charged negatively.
- the surface of the photosensitive drum 6 is cleaned by a cleaning unit 16 to prepare for next image recording.
- the transparent film 4 on which the original image is transferred stops between a light source unit 9 consisting of a light source 9A, a shutter-diaphragm 9B and a condenser lens 9C and a projection unit 10 consisting of a condenser lens 10A and a diaphragm 10B disposed at the same position as the light source unit 9 so that an optimal quantity of light is projected to the imaging sheet 1.
- the original image is cleaned off from the transparent film 4 by a cleaning roller 22 and the transparent film 4 is taken up on a reel 4B. When the transparent film 4 is fully used up, it is rewound on the reel 4A for re-use.
- the image of each of yellow, cyan and magenta is formed on the film separately by the method described above.
- Color filters for yellow, cyan and magenta are disposed in the color filter 7 and are sequentially moved by driving means, not shown, to make color separation of the light projected from the light source unit 9.
- the light source unit 9 projects the original image light once per each color corresponding to each color of the color filter 7 to the imaging sheet 1.
- the three colors of yellow, cyan and magenta are projected to the imaging sheet 1 for color recording.
- a light modulator such as liquid crystal shutter or a PLZT shutter, in place of the laser scanner unit 5 described above.
- FIG. 2 shows the second embodiment of the present invention.
- Microcapsules sealing therein a photo-reactive composition and a chromogenic materials which generates color upon reaction with a developing materials applied on an image-receiving sheet 2 are applied on an imaging sheet 1.
- Back-tension is applied to the imaging sheet 1 by rollers 11 to form a flat surface portion onto which a later-described original image is to be projected.
- a pressure roller unit 3 is disposed downstream of this flat surface portion. While the photo-sensitive surface of the imaging sheet 1 and the developing materials-coated surface of the image-receiving sheet 2 face each other in superposition, the microcapsules are ruptured, react with the developing materials so that coloration proceeds and a color is outputted.
- a laser beam is radiated by the laser scanner unit 5 on the basis of signals from an image data processing circuit or output signals of a computer, not shown, and the charge of the laser beam radiated portion is removed so as to form the latent image of the image.
- the latent image formed on the photosensitive drum is transferred onto a transfer unit 20, which is in point-contact with the outer periphery of the photosensitive drum 6, consisting of a glass substrate 20A, a transparent Nesa film 20B and a dielectric film 20C. In other words, the residual charge on the drum is transferred onto the dielectric film 20C.
- the surface of the photo-sensitive drum 6 is cleaned by a cleaning unit 16 to prepare for next image recording.
- a toner is then deposited by a developing unit 19 to the transfer unit 20 to which the latent image is transferred.
- the transfer unit 20 is moved between a light source unit 9 and a projection lens unit 10.
- the cleaning device 21 is away from the transfer unit by mechanical means such as cams.
- the light source unit 9 consists of a lamp 9A, a shutter-diaphragm 9B and a condenser lens 9C.
- Diaphragm and shutter time are regulated for each filter so that the light which permits the microcapsules to cause the most efficient coloring reaction is projected to the imaging sheet 1. In this manner, high quality color image recording is carried out.
- the present invention can easily form the plural and large size monocrome pictures which are converted from output signals of the computer and used for image original.
- the utilization of the image original does not require the scanning time increasing in propotion to the increased numbers of copies of an image, so that the color printing system of the present invention can make continuous recording and high speed recording by a simple mechanism.
